What is 3D printing?
3D printing or additive manufacturing is a process that produces tridimensional objects starting from a digital file. The creation of the 3D printed object is based on the additive process, which involves depositing the material in successive and horizontal layers until the object is fully created. Each of these horizontal layers can be seen as a thin horizontal ‘slice’ or the section of that object.
To prepare a digital file for printing, special software is used to ‘”slice” the final model into hundreds or thousands of horizontal layers. When the file is uploaded to the 3D printer, the object can be created layer-by-layer.The printer reads each “slice” (or 2D image) and cerates the object, gluing every layer with a very subtle distinctive differentiation ( which can be completely eliminated by a fine grinding).
